The answer would be 7.225.
You know 10 students are 100%
so that we have : 7 students are 7/10 x 100 = 70
the angel you would use in a pie chat is : 70 x 3.6 = 252
Answer:
Hello, Have a good day
Step-by-step explanation:
The slope of the perpendicular line is the opposite sign and the inverse of the original line's slope.
(-1,-2) and (0,0).
slope = (0 - -2)/(0 - -1) = 2/1
So ,inverse and opposite would be -1/2
A parallel line has the same slope with a different y intercept
-2 = (-1/2)(-1) + b
-2 = 1/2 + b
b = -5/2
So, same slope, different b (y intercept) for a parallel line.
So 3x=6+4y
divide both of the equations by 3
x=2+4y÷3
x=2+4/3 y
your answer
x=2+4/3 y hope this will help
Answer:
Null hypothesis : 
Alternate hypothesis : 
Step-by-step explanation:
To Find : State the hypotheses to be tested.
Solution
Mean = 72
Standard deviation = 20
N = 30
Claim : Shorney Construction Company bids on projects assuming that the mean idle time per worker is 72 or fewer minutes per day.
So, Null hypothesis : 
Alternate hypothesis :
